proof or cork insole for boots and shoes;and

the improvement consists in splitting the leather insole to form the twostrips between which the cork sole or like water-proof ma? terial isinclosed and cemented.

In the accompanying drawings, Figure 1 is a plan view of the leatherinsole as shaped before being skived or split. Fig. 2 shows alongitudinalcross-section of the same after splitting. Fig. 3 is alongitudinal section through the completed insole, showing the inclosedcork sole, and Fig. 4 is a cross-section of the same. v

In the manufacture of that class of waterproof insoles the improvementof which is contemplated in this invention the cork sole is inclosedbetween a lower sole-leather insole and a superposed thin inner liningof greater length and width than the leather insoleand cork sole, withthe overlapping edges of the lining turned over and fastened upon theinsole, as shown and described in Letters Pat= ent of the United Statesissued to me October 13, 1885, and numbered 328,267.

The object ofthis invention is to dispense with the thin inner liningheretofore used, and to employ the leather insole only and the cork inthe construction of my improvedinsole.

The improvement is more particularly adapted to that class of cork soleshaving the cork extending from the toe to the shank or hollow of thefoot only, as shown in the accompanying drawings, in which A representsthe leather insole, B the part skived or split therefrom, and C denotesthe inclosed cork sole or like water-proof material.

The leather sole is first shaped, with an overlapping edge, (2, aroundthe part or portion which is to inclose the cork sole. From the underside of the insole A a strip, B, is skived or split off, comprisingrather more than onehalf of the entire thickness of the leather. Thestrip B tapers down to a sharp edge near the shank or hollow of thefoot, and is cut to the shape desired, as shown by the dotted lines inFig. 1. The cork sole 0 is shaped to correspond to the part B, and theoverlapping edge e of the main part of the sole is trimmed or shaveddown to a sharp edge. The cork sole is then cemented between the twoparts the upper, as shown by the threads at in the drawings.

The cork sole may extend farther back than is shown in the drawings; butthe invention is especially adapted tbr use where the cork sole isrequired to extend back only as far as the shank or hollow of thefoot-that is to say, over that part of the sole most exposed todampness.

In the construction of this insole only one piece of leather isrequired, thus reducing the cost of its manufacture, and sole-leatheronly is used, thereby producing a stronger sole. By this construction,also, the edges of the'insole are not sharp and angular, but wellrounded, and do not therefore abrade or cut the upper at its joint withthe sole, thus increasing the durability of the shoe.

I claim as new and desire to secure by Letters Patent In a boot or shoe,a water-proof insole consisting of a cork sole or like waterproofmaterial interposed between the two strips or portions A B of a leatherinsole, the leather insole being skived or split from the toe to theshank'or hollow of the foot, and having its main or upper part providedwith an overlapping edge, e, which is turned over upon and secured tothe lower or lesser part, thus inclosing the cork sole between the twoparts I of the leather insole, substantially as and for the purposespecified.
